[Elecraft] Buying a KRX3 - Filter selection help needed!

[Edward R Cole]

I have installed in the main Rx: 13.0, 2.8 KHz, and 400 Hz 
filters.  I chose to install a 2.8 KHz filter in the sub-Rx.  The 
13-KHz filter is for VHF-FM and I do not need diversity reception for 
that.  With the 2.8-KHz filter in both Rx I can do diversity on all 
modes except FM/AM.  I am not in a high-density ham population where 
having a roofing filter for diversity CW is needed.  The DSP filter 
is adequate.  I run VHF diversity reception using two LP-Pan so the 
roofing filters are not even used as signal is diverted to the 1st IF 
(in fact for MAP65 I select IFIL3 which is an empty slot to avoid 
signal suck-out at 8.215 MHz).

Even for non-diversity operation a single SSB filter offers the most utility.
